We use collected data to:

The Jdar App requests the following device permissions:

Camera: Scanning QR codes at community gates and uploading photos for service requests and documents

Bluetooth: Detecting nearby gates and opening barriers via Bluetooth Low Energy (BLE)

Photo Library: Selecting photos for profile pictures, service requests, and document uploads

Notifications: Receiving push notifications for service updates, visitor approvals, and announcements

You may manage or revoke these permissions at any time through your device settings.

– Server-side: Your data is stored in secure databases (PostgreSQL) and encrypted file systems accessible only to authorized personnel.

– On-device: Authentication tokens and Bluetooth security keys are stored in your device’s secure storage (iOS Keychain / Android Keystore).

– Edge Devices: Gate controllers (Raspberry Pi units) store minimal credentials locally in encrypted SQLite databases.

– All data transmitted between the app and our servers uses HTTPS/TLS encryption

– Passwords are bcrypt-hashed and never stored in plain text

– Bluetooth communications use HMAC-SHA256 signed requests and AES-256-GCM encryption

– Authentication tokens have limited lifetimes and are rotated on use

– API access is rate-limited and protected by device binding (one device per account)

– Admin actions are audited with IP address logging

We retain your personal data for as long as your account is active or as needed to provide our services. You may request account deletion by contacting us (see Section 8). Government-issued ID documents are retained as required by applicable regulations.
